Passes all tests and QA script. Tested:

- Record with 1 lost item, result list = 1
  - Verified without both patches 404 error page is shown
  - Verified with 1st patch, no results page is shown
  - Verified with 2nd patch, the still showing facets are gone
- Record with 1 lost item, result list > 1
  - Record is hidden from result list, but
    - result count is wrong
    - result numbering is wrong
    > This is an old problem, just noting
- Record with 1 lost and 1 available item, result list = 1
  - Detail page is shown, only lost item is hidden
- Record with 1 lost and 1 available item, result list > 1
  - Only available item is shown in result list

Also checked that the lost item shows up with hidelostitems off.
